  1. A New Paradigm forE-Groceries IS 485, Professor Matt Thatcher

  2. Things to Note About this Case(Form and Presentation) • Description of the problem • Findings from the contextual inquiry • Discussion of the design solution and rationale • Presentation of usability problems and feedback uncovered during user testing • Discussion of recommendations

  3. Initial Design Conceptualization(May 1998) • Electronic catalog of store products • graphical images of product categories (to match the physical catalog used with Collect & Go) • physical store layouts and walking the aisles

  4. Contextual Inquiry • 2 visits to Safeway • asked Collect & Go customers how they put their orders together, likes/dislikes, problems • Findings • shopping is a chore • shoppers often buy the same stuff each week • key for shoppers is to save time • do not want home delivery • big problems when personalized list is unavailable • Collect & Go Shoppers are concerned they are missing out on new products and special offers • do not use the physical catalogue very much (focus is on the personal list)

  5. Design Solution and Rationale • Abandoned electronic catalogue • based on contextual inquiry findings • New design (after several iterations) • expanding tab control • visibility, efficiency, saves space • 5 lists • personalized list became the focus of the application • offers, ideas, loyalty points, order • functions • find, request, and specify delivery time and date • shopping basket metaphor • so the order shows up in 2 places (personal list and order tab) • no graffiti required

  6. User Test Results(December 1998) • Users had problems: • parsing the screen • perceiving boundaries • confirming products were added to an order • using the Palm keyboard • making tapping errors (clicking on wrong areas)

  7. Recommendations(This is very brief – see case for details) • Create a wallet card (short training) • Create better crucial distinctions for boundaries • thicker lines, better spacing, maximize dialog boxes • Tag items in lists with icons • Develop a custom keyboard • change keyboard to request • Better clues to confirm item added • visual and audio clue added • Increase tap-sensitive region around navigation buttons • Put icons next to items on personalized list

  8. Let’s Talk About the Interactive Demo

  9. Class Discussion • Alternative designs?
